Step 1: Determine the UTF-8 encoding bit layout
The character ⊆ has the Unicode code point U+2286. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800
to0xffff
.
Therefore we know that the UTF-8 encoding will be done over 16 bits within the final 24 bits and that it will have the format:1110xxxx 10xxxxxx 10xxxxxx
Where thex
are the payload bits.UTF-8 Encoding bit layout by codepoint range Codepoint Range Bytes Bit pattern Payload length U+0000 - U+007F 1 0xxxxxxx 7 bits U+0080 - U+07FF 2 110xxxxx 10xxxxxx 11 bits U+0800 - U+FFFF 3 1110xxxx 10xxxxxx 10xxxxxx 16 bits U+10000 - U+10FFFF 4 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx 21 bits Step 2: Obtain the payload bits:
Convert the hexadecimal code point U+2286 to binary:
00100010 10000110
. Those are the payload bits.Step 3: Fill in the bits to match the bit pattern:
Obtain the final bytes by arranging the paylod bits to match the bit layout:
11100010 10001010 10000110
SUBSET OF OR EQUAL TO·U+2286

Description
The Unicode character U+2286, known as "Subset of or equal to" (⊆), is a mathematical symbol that plays an essential role in digital text, particularly in computer science and mathematics. It is often used in set theory, algorithms, and logic to denote the relationship between two sets where one set is either a subset of or equal to another. The character represents this relationship as "A is a subset of or equal to B," emphasizing that A's elements are all part of B or A is completely identical to B. While U+2286 is primarily used in technical and mathematical contexts, its applications can also extend to other fields requiring set theory, such as computer programming, data structures, and computational mathematics.
